Which manufacturer or remanufacturer is best?
It’s hard to say, but if we’re just talking about Diesel Injector, Delphi is the best one on this list.

The refundable core deposit system implemented by BuyAutoParts is probably the single most compelling thing about this product: First, you make a deposit (of about 100$).

03. HEUI Injector for Ford 7.3 Powerstroke or International T444E by Alliant Power – The real power of diesel
- Original HEUI-type injector
- Brand new
- Built for top performance
HEUI is just an acronym for Hydraulically activated, Electronically controlled Unit Injector.
This was basically the first instance of direct injection that the world has seen, and is an excellent milestone for automotive engineering.
What Alliant power offers is top-notch quality equipment that is hardly bested by other brands.
Their injectors (and most of their products) are quite famous for being some of the most lasting and reliable on the market.
Plus, this is new equipment. Some people have their reserves about buying remanufactured equipment (if it failed once…), which is why there are options like these.
Most of the time, what you really want is a brand new part. It’s just more expensive, so you get the remanufactured one.
But of course, even if you’re getting it now, you can still give up your old, defective injector in exchange for a 100$ refund, which is, considering the price, quite a relief.
- New & shiny!
- It is built to be just as good as your original injector.
- Perfect fit.
- Very powerful
- A bit expensive
This is an excellent choice for people who want their replacement to be of the highest quality possible.
If money is no object and you don’t want to get anything but the best, then this is the one for you!
04. Delphi EX63803AD Diesel Injector – Best Alternative for High Quality
- Performance and quality tested
- Parts are all new and high quality
- Made in America
And we say alternative because, unlike Alliant Power, this company is based in Dublin, Ireland – not at all because of the quality of the product.
Delphi’s manufacturing is also top-notch, and although their administrative headquarters are in Ireland, they make most of their parts in the US.
But, like with doctors, sometimes we want a second opinion. Sure, you want to get the best injector possible, money being no object, but do you have just one choice? The answer is Delphi.
Delphi’s mission is not just to manufacture (and remanufacture) auto parts upholding the strictest standards they can; they aim to better their techniques and so better the parts – improving upon the quality of their craft so as to make a better one each time.
This product has undergone supervised tests to ensure that it can match the performance giving by original injectors.
- A good alternative to Alliant
- Undergone supervised performance tests
- All injector parts are new
- No core refund
This injector is a great choice that’ll make your car run even more smoothly than before. Delphi is not just a manufacturer: These guys are basically scientists.
And who else are you gonna trust to give you the best technology and engineering, besides scientists?

- Premium quality
- Precise fuel injection
- Can handle extensive wear & tear
While Bostech might be a more small-scale kind of manufacturer compared to others on this list, their Gold Series Injector might as well be their crown piece.
It is of exceptionally high quality, with some of the best remanufacturing work – hardly anything to complain about.
This Injector (for cylinder #8) is Bostech Factory certified – their remanufacturing methods have been tested regularly over the years to ensure that they are consistent with the quality of their products, and that is particularly true with this injector.
In terms of market popularity, Bostech may not be the first thing that comes to your mind; we admit it.

What we liked about this kit is that first, the installation tools are incredibly sturdy – they could probably handle hundreds of cylinder installations (hope it doesn’t come to that though) before so much as a chip appearing on them.
Second – the parts that come with these tools as part of the kit are surprisingly high-quality.
Most mechanics would recommend you buy stuff like this separate, but we think you’ll be pleasantly surprised by the quality of this kit.

Get this kit if you’re enthusiastic about your car so that you wouldn’t trust some stranger doing work on it – the only way for you to make sure the job’s done right is to do it yourself.
09. Fuel Injector Sleeve Cup Removal Tool & Install Kit, Injector O-Ring Kit – The complete kit ever
- Comes with O-ring kit
- Easy to use
- Works great
While the O-ring equipment might be just a little plus, it does come in handy even after many uses. The point of this kit, after all, is convenience.
Do not expect a tip-of-the-spear kind of kit: This is not designed to be particularly high quality, but it’s more to get you out of a hairy situation.
After all, these guys understand that some people don’t really need tools that’ll last them a lifetime: It’s a one-time thing, does the job, get out.
And that’s the strength here – the kit is very affordable if you take into account of much stuff you get, it ships immediately, and it’s straightforward to use. Cheap, fast, convenient. That’s all you need, really!

What can be said for this kit? After all, it’s not particularly attractive. Sure, it’s made in China: that might spell cheap, but…

Buyer’s Consideration Ford 3.7 Powerstroke Engine Injectors
How do we make sense of all this, then? To make a decision, it’s better to break down what influences the decision – like price, reliability, the convenience of the product, and so on.
So, let’s look at different factors separately so you can get a sense of which decision is the right one for you:
Yes. Whether a product is reliable or not is a huge, significant factor in whether or not someone will buy it. But this is a very subjective thing.
While one manufacturer might be generally regarded as making reliable parts, one bad experience from a source you trust -or even yourself- might make the winds shift.
Further than just predicting the quality of the product, this serves to feel better about our decision.
Even if a part is alright, if you had doubts before buying it, you will feel like something just ain’t right with the car – also if there’s nothing wrong. Kind of like the placebo effect, but with diesel injectors.
A most apparent consideration: Can I afford this?
The answer is complicated- Even if you can afford the highest price, is it wise to spend all that money? Could you be paying just because of the manufacturer’s name?
This is for you to consider: What are you paying for, and is it worth it for you? For example, while two injectors might look exactly the same.
You might feel strongly in favor of the more expensive one just because it comes from a reputable manufacturer: If this is very important for you, then that’s your choice – if not, then you can look at lower prices.
Then comes convenience – which is a very diverse category, for example; Does this installation kit provide the bare necessities for removal and installation, or does it have some spare parts that could come in handy later, for something else?
As another example, you can find it more convenient for your needs to buy apart from a provider that offers extensive customer service if you feel it imperative to have each and every question about the product answered.
A warranty (and its length and price) can fall under this category.
Frequently Asked Questions about 3.7 Powerstroke injectors
Do more significant injectors increase MPG?
Technically, yes. They can – but not if you tune your car right. If you just swap injectors and don’t pay attention to anything else, it’ll definitely increase mpg.
How many injectors does a 7.3L Powerstroke have?
It depends on the particular engine, but usually 8.
What CC do these injectors have?
They commonly range from 80 to 130 cc.
How many injectors does a 6.7 Powerstroke have?
8 as well.
So, after all of this, we wish that this article can help make a better decision now that you’re informed and, more importantly, more aware of each product’s pros and cons.
We do recommend, however, that you read each product review twice for good measure.
It’s easy to get dazzled by one product in particular and become blind to possible faults and things you won’t like until after you’ve bought it, so take your time.
